Directory must be an object that can be converted into a pathname
->pathname. The directory specified by directory is
read, and the contents of the directory is returned as a newly allocated
list of absolute pathnames. The result is sorted according to the usual
sorting conventions for directories, unless sort? is specified as
#f. If directory has name, type, or version components,
the returned list contains only those pathnames whose name, type, and
version components match those of directory;
#f as one of these components means “match anything”.
The Windows implementation supports “globbing”, in which the
? are interpreted to mean “match
anything” and “match any character”, respectively. This
“globbing” is supported only in the file part of directory.
